ALSA audio

ALSA is the Advanced Linux Sound Architecture. Isis provides an
interface to some of the functionality of ALSA, mainly for playing and
recording audio. This low-level interface is described briefly below.
More detailed documentation will be added soon. See the ALSA
online documentation for more information.

There are also high-level platform-independent audio utilities available. These
utilities are easier to use and sufficient for most audio
applications. Please consider using them first.

As of February 2003, Isis uses ALSA version 0.9.x. We highly
recommend upgrading your version of Isis to take advantage of the
improvements in the sound library. You will need to make some small
changes to any Isis programs that used the older version of ALSA.
Contact Stefan for more information. The documentation below is for
systems with ALSA 0.9.x.
